Transurethral removal of a cystic urolith in a mare using a laparoscopic specimen pouch

CASE REPORT

Cystic urolithiasis is the most common form of urolithiasis reported in horses. In contrast to the gelding or stallion, clinical disease is less common in the mare and manual removal techniques are possible because of their shorter, wider urethral anatomy. However, these manual removal techniques can be traumatic and are limited by the size of the urolith. This report describes the use of a commercial laparoscopic specimen pouch to remove a cystic urolith in a mare.

CONCLUSION

This approach may allow the extraction of larger uroliths per urethra in the mare, while affording some protection to the mucosa of the bladder neck and urethra.

Urinary clinical pathologic findings and glomerular filtration rate in the horse

Urinary specific gravity (USG) measurements are underused by equine ambulatory veterinarians. Urinary dipstick and USG findings can assist in the diagnosis and prognosis of many disease processes in the horse. Simple methods for measurement of the glomerular filtration rate and urinary biochemical markers can improve equine urinary diagnostic abilities in critical care patients. Fractional excretion of electrolytes and minerals assists in fluid care and in management of nutrition of horses.
